Scientists in the field of genetics have made a breakthrough that could have major implications - they have successfully created a generation of blastocyst-like spliceosomes that can repress gene expression in mice. This is the first time that a spliceosome of this kind has been created and could be a major step forward in understanding how gene expression is regulated. This could potentially lead to the development of new treatments for certain diseases and other conditions.
